Actually, Blaziken
could pass speed and SDs if it for some odd reason found itself in a bad matchup. However, in response to
Shinji Mimura, you might want to take a look at a tournament called
Gods Among Us, currently in its third round where Blaziken is allowed alongside the OU mons. Right now the consensus seems to be that although Blaziken can no longer pass, it still has Speed Boost alongside being hella powerful and having actual bulk (unlike, say, Sharpedo), so it's still too much at this point.
Ninja'd, but whatever.
